I have an Asus P5W-DH Deluxe, and my current BIOS revision is 1305. I was wondering if the reason I cannot boot a Leopard DVD is because my BIOS is relatively old compared to the current revision 2602. Is it worth the risk to flash it? I haven't ever flashed a BIOS before so I don't have any idea how yet, but I want to know if there is any need to because I hear it can be a risky procedure. Thanks in advance for your input!
